About 5mo ago i accidentally washed my original 2001 S430 car key. After being in washer machine for an about 45 minutes it still works. LOL
MB will not reprogram your key fob, unless you buy it directly from them. In most states is $250 for a new key.
Thank you in advanced

They're only good for the outer shell.
The Keyless Go key has a wider PCB piece inside the black key. I can only surmise that the old technology will not fit into the new chrome key, where a new PCB must be used.
If you buy a chrome key from ebay and try to swap the insides of your black key to the new chrome key, make sure the buttons are at the correct location and the ignition induction coil (of the guts) is in the same location relative to the front of the key.
By looking at the key pictures on ebay i decided that they are not compatible and therefore did not by any to swap the key guts (PCB) into.
Can you open it up and see.

I see that the IC is surface mount soldered. I can solder it off but how much heat does the IC stand? Do i need a heat sink? When re-attaching onto the new PCB can i do that cold; with paste?

You must be careful removing the IC as not to damage it whatsoever, you can resolder with normal temp 500-600F, can not do it cold. Oh yeah, need to be done under a microscope, you don't want to short any thing.
By the way, I have successfully done this about a dozen times helping out fellow car enthusiasts, worked every time:

Mercedes is very strict about this. If your key doesn't work and you can't start your car , they will make you tow the car to them . They used to just give out the key but I guess it resulted in some cars getting stolen and lawsuits

There is now a couple of non Mercedes shops with the capability to make keys and they don't care about seeing your car or the registration. Sorry I don't have the contact info but the have been mentioned in other recent threads this year about keys



That price is the same as quoted at my local dealer. Paylesscarkeys also need to have the car in order to do programming.
I haven't check the other site.
